0 – 1.75 UI/L
0 – 1.75 UI/L
0 – 1.75 UI/L
What does a low result mean?
A negative reading under 1.75 UI/L confirms absence of abnormal autoimmune receptor stimulation.
What does a high result mean?
A positive finding reveals autoimmune stimulation of the gland, helping tailor gentle, temporary thyroid therapies.
Questions ready for your doctor

- Does this explain any recent heart rate or energy fluctuations?
- Is mild, temporary medical treatment indicated to restore comfort?
- Will a recheck in two months follow the clearance of these antibodies?
